Jackie 'O' Henderson's debut single has been pulled after it reached number one on the iTunes Australia chart.

Last week, the KIIS FM host wrote and recorded the song 'Honey Money' after being challenged by her co-host Kyle Sandilands.

The single was released on iTunes earlier this week with all proceeds going to the charity Drought Angels to support Aussie farmers.

On Wednesday morning, Henderson was overjoyed to learn she had a number one single, but it all came crashing down on Thursday.

"We now have to take it down," the 43-year-old told Beau Ryan (who is filling in for a sick Sandilands) on air this morning.

You see, instead of creating their own cover art for the single, the KIIS FM team simply photoshopped Henderson's head onto a photo of Iggy Azalea's body.

Not only does the photoshop job look... terrible, but it's also a copyright issue.

"The cover art work is horrific," Henderson admitted. "It's my head really badly photoshopped onto someone else's body. I didn't know who it was… It looked a bit like a pisstake. You were trying to make me look hip hop or something."

"Anyway, Intern Pete has apparently chosen Iggy Azalea's body for me to be photoshopped on and that is a copyright infringement and we now have to take it down until we get new art work," she explained.

Unfortunately, in order to change the cover art, iTunes need to completely pull the song down and Henderson will have to re-upload it.

"The problem with this is, when you take it down, the people who have bought it... have to re-buy it and that's not cool," Henderson said. "So when we put it up again it will now be for free so that the people who did buy it can still have it and anyone else can have it for free. This is such a disaster."

Henderson urged listeners to download the re-uploaded track for free, but to also donate to Drought Angels directly.
